Abstract

An oxidation catalyst, comprising a carbon material prepared by calcining a transition metal compound and a nitrogen-containing organic substance, or a transition metal compound, a nitrogen-containing organic substance, and a carbon compound not containing nitrogen, the oxidation catalyst oxidizing at least one target substance selected from the group consisting of NO, CO, NH 3 , and an aromatic hydrocarbon.

1 . An oxidation catalyst, comprising a carbon material prepared by calcining:
 a transition metal compound and a nitrogen-containing organic substance, or   a transition metal compound, a nitrogen-containing organic substance, and a carbon compound not containing nitrogen,   the oxidation catalyst oxidizing at least one target substance selected from the group consisting of NO, CO, NH 3 , and an aromatic hydrocarbon.   
     
     
         2 . The oxidation catalyst according to  claim 1 , wherein the target substance is oxidized at a temperature of not less than 10° C. 
     
     
         3 . The oxidation catalyst according to  claim 1 , wherein the target substance is an aromatic hydrocarbon, and the aromatic hydrocarbon is oxidized at a temperature of not less than 200° C. 
     
     
         4 . The oxidation catalyst according to  claim 1 , wherein at least one load material selected from the group consisting of Pd, Rh, Ru, Ni, Co, Fe, Ce, Cu, Ti, Zr, Sn, V, Nb, Ta, Cr, Mo, W, Bi, Mn, and compounds thereof is supported on the carbon material. 
     
     
         5 . An adsorbent, comprising a carbon material prepared by calcining:
 a transition metal compound and a nitrogen-containing organic substance, or   a transition metal compound, a nitrogen-containing organic substance, and a carbon compound not containing nitrogen,   the adsorbent adsorbing at least one target substance selected from the group consisting of NO, NO 2 , formaldehyde, and acetaldehyde.   
     
     
         6 . The adsorbent according to  claim 5 , wherein the target substance is adsorbed at a temperature of not less than 10° C. 
     
     
         7 . A material for purging harmful substances, comprising at least one of the oxidation catalyst according to  claim 1  and an adsorbent comprising a carbon material prepared by calcining:
 a transition metal compound and a nitrogen-containing organic substance, or 
 a transition metal compound, a nitrogen-containing organic substance, and a carbon compound not containing nitrogen, 
 the adsorbent adsorbing at least one target substance selected from the group consisting of NO, NO 2 , formaldehyde, and acetaldehyde. 
 
     
     
         8 . A material according to  claim 7 , wherein in the adsorbent, the target substance is adsorbed at a temperature of not less than 10° C. 
     
     
         9 . A material according to  claim 7 , wherein in the oxidation catalyst, the target substance is oxidized at a temperature of not less than 10° C. 
     
     
         10 . A material according to  claim 7 , wherein in the oxidation catalyst, the target substance is an aromatic hydrocarbon, and the aromatic hydrocarbon is oxidized at a temperature of not less than 200° C. 
     
     
         11 . A material according to  claim 7 , wherein in the oxidation catalyst, at least one load material selected from the group consisting of Pd, Rh, Ru, Ni, Co, Fe, Ce, Cu, Ti, Zr, Sn, V, Nb, Ta, Cr, Mo, W, Bi, Mn, and compounds thereof is supported on the carbon material.
